Secure and Distributed Data Discovery and Dissemination in Wireless Sensor Networks - 2015
A knowledge discovery and dissemination protocol for wireless sensor networks (WSNs) is accountable for updating configuration parameters of, and distributing management commands to, the sensor nodes. All existing data discovery and dissemination protocols suffer from two drawbacks. 1st, they are based on the centralized approach; solely the bottom station can distribute information things. Such an approach is not suitable for emergent multi-owner-multi-user WSNs. Second, those protocols were not designed with security in mind and hence adversaries can easily launch attacks to hurt the network. This paper proposes the primary secure and distributed information discovery and dissemination protocol named DiDrip. It allows the network house owners to authorize multiple network users with completely different privileges to simultaneously and directly disseminate information things to the sensor nodes. Moreover, as demonstrated by our theoretical analysis, it addresses a number of doable security vulnerabilities that we have identified. Extensive security analysis show DiDrip is provably secure. We conjointly implement DiDrip in an experimental network of resource-limited sensor nodes to indicate its high efficiency in apply.
